cant drag floor point in archipack
I tried an approach that often works for me in recovering from blender trickery ;-)
I started a new blend app session, &quot;File :: Append&quot; the old file, and things started working again.   As I had only a lowly 16 GB RAM, I set 3d-view to solid (not Material Preview) as compiling the Material renders would blow my memory limit.
With this workaround, there's no telling how many times you may need to recover, as you'll need to report this bug to the Archipack community.
